The Nye Committee of the 1930s is most closely connected to which of the following?

The Gulf of Tonkin Resolution was passed in 1964 and authorized military action in Vietnam, thus reflecting the escalation of U.S. involvement in Southeast Asia. This event occurred long after the Nye Committee's activities in the 1930s and is unrelated to the committee's focus on isolationism and the potential consequences of military entanglements.

The Roosevelt Corollary, articulated in 1904, expanded U.S. intervention in Latin America under the guise of protecting American interests. While it marked a shift towards interventionist policies, it predates the Nye Committee and does not align with the committee's emphasis on isolationism.

The Truman Doctrine, established in 1947, aimed at containing communism through political, military, and economic assistance to countries resisting Soviet influence. This was a post-World War II strategy, contrasting sharply with the Nye Committee's advocacy for isolationism and neutrality in the 1930s.
